Teeth names are created by a combination of 4 different characteristics: 1  The jaw where they are located: upper and lower (alternatively the terms maxillary and mandibular can be used) 2  The side of the face: left and right.  The type of tooth: incisor, canine, premolar, and molar.
Vampire bats are members of the New World Leaf-nosed bats, the Phyllostomidae. All three species of living vampire bats occur in South and Central America. Fossils of three other species reveal that several thousand years ago vampire bats were more widespread.
There are only three bat species that actually feed on blood: The Common Vampire Bat (Desmodus rotundus), the Hairy-legged Vampire Bat (Diphylla ecaudata) and the White-winged Vampire Bat (Diaemus youngi). All three species are native to the Rainforests of America, ranging from Mexico to Brazil, Chile, and Argentina.
